“When the wick was lit, a gallon jug filled with gasoline didn’t ignite as one might suspect. Gasoline itself doesn’t burn—its vapors do. The narrow opening at the top of a jug allowed only so many vapors to escape at a time. The gasoline itself acted as a coolant, letting the device burn as slow and steady as a kerosene lamp. It could be 21 minutes before the jug’s plastic melted, allowing the gasoline and its accompanying vapors to spread across the porch. Once it did, the fire would reach the wood or aluminum siding.”
